COT FOB INVALIDS.

Specification of Letters Patent.

Patented July 14, 1914.

Application filed August 28, 1913. Serial No. 787,113.

To all whom it may concern;

Be it known that I, Jnssn H. Kmnnion, a resident of Valley Center, inthe county of Sedgwick and State of Kansas, have invented certain newand useful Improvements in Cots for Invalids; and I do hereby de-i clarethe following to be a full, clear, and exact description oftheinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to adjustable cot for. invalids and cripples, andhas for its object to provide a cot that can be adjusted to suit variousconditions and is more especially adapted to persons having a brokenleg, who, during their confinement have to be continuously in oneposition, until the bones knit together.

One of the objects of my invention is to provide a means whereby thepatients leg can be placed in various positions and still be kept inproper condition to allow the said bones to properly unite.

I attain these objects by the means illustrated in the accompanyingdrawings, described in the specification and the appended claims.

Referring to the drawings, Figure 1 is a perspective view of my device.Fig. 2, an end View, and Fig. 3, a plan view in. part of Fig. 1, showinga reticulate fabric positioned on the top section of my device, on whichrests the patient, said fabric not being shown on Fig. 1, in order tomore fully disclose the mechanism thereof.

Similar numerals designate similar parts throughout the several views.

My device is substantially in two sections, 1 and 2, and is of a heightpreferably to bring it when in a normal position on a plane with thebottom of a chair but can be used under the patients leg when in bed andis substantially of a size to receive the patients entire body; section2 being positioned above section 1. Said sections are transversely andlongitudinally adjustable. Said sections are composed of sub-sections3-3-3-3, are slidably connected together by means of keepers 4 aiiixedthereto by -ivets 7 a plurality of holes 5 are made in said members sothey can be adjusted to any desired position and rigidly aflixed bybolts 6. It is obvious the structure can be lengthened or narrowed asdesired. A portion of the lower section is flattened down as at 1'7, afeature that will be referred to later.

similar wheel 26 defined in To the lower section is pivotally affixed asat 12 and 34, upwardly extending arms 8 and 9 and on the arm 8 are cogs35. The arms 9 are in two sections and are pivotally connected togetherasat 10 and can be made rigid by placing bolts in the holes 11. One endof section 2 ispivotally connected to the top ends of the arms 9 as at12 and the opposite end of said section is made to swing up and down bymeans of a geared mechanism. An arbor 23 is journaled in the uppersection and has afiiXed thereon a pair of spur-wheels 24, which engagethe cogs 35; lugs 38 aiiixed to the adjacent bars, hold the arms incontact with the spurwheels 24. On the end of said arbor is placed abevel wheel 26 which engages a on an arbor 25 which extends along thesections 3, being journaled in bearings 27 welded to said sections (apiece thereof being removed to show the connectionof said section) andhas aflixed thereon a thumb-knob 28. It is obvious that when the knob 28is turned, the free end of the upper section will be moved up and downon the arms 8 until it reaches a horizontal position indicated by thedotted lines 16 in which position said sectionwould be on a plane withthe bottom of a chair and held in that position by apin 29, passedthrough the arbor 25, which contacts the adjacent bar, and by means ofthe braces 13 and the bolts 1414, the upper section can be made rigid inits upper or lower position.

If the patient is required to lie on his back in bed and it is desiredto elevate his leg a certain distance, it can be accomplished byremoving the bolts 11-11 and the arms 99 can be moved down as indicatedby the dotted lines 3636 until the top section would be in the positionindicated by the dotted lines 1515, bringing the end of the top sectiondown on the end of the flat portion 27 of the lower section. If thepatient wanted to sit on a chair, the device would be put in theposition as shown in Fig. 1, which would let the foot down near thefloor.

Over the entire section 2, I stretch a reticulated fabric 22, on whichrests the pa tient, which is held in proper position when fastened to aseries of pins 21 in the top section and when an adjustment is made inthe length or width of said section, the said fabric can correspondinglybe ad usted on the pins 21. To the free end of section 2,

proper size, will prevent muscular contracr.

tion and allow a broken bone to properly knit together and therebyprevent shortening of the leg. I I

Then the patient is too heavy on the fabric 22, it tends to draw thesides of the.

top section together; This I prevent by placing a curved brace 18therebetween and aflixed thereto with bolts 2020. Said brace is providedwith a plurality of holes and is adjustably held together with a bolt19.

Having described the construction and assembling of my device, what Iclaim is' 1. In a cot for invalids substantially in two sections, eachsection beingcomposed of a plu ra-lity of sub-sections, means for,adjusting said sections whereby the cot may be expanded or contracted,arms in two sections pivotally connecting the first named sectionstogether, means to make said arms rigid, and a brace to make said armsrigid with the lower section, armsh'aving cogs thereon pivotallyconnected to the lower section, an arbor journaled transversely in theupper section, spur-wheels mounted upon said arbor to engage the cogs onthe aforesaid arms, and means for rotating said spur-wheels to positionthe free end of the upper section in any desired position and means tohold the cogs on the said arm incontact with thespurwheels. v 1 2. In acot for invalids substantially in two sections, each section beingcomposed of a plurality of sub-sections, means for adjusting saidsections whereby the cot may be expanded or contracted, arms in twosec-' tions pivotally connecting the first; named sections together,means to make said arms rigid, and a brace to make said arms rigid withthe lower section, arms having cogs thereon pivotally connected to thelower secsection in any desired position and means to hold the cogs onthe said arm in contact with the spur-wheels, a sheave affixed to thefree end of the upper section and a rope to play over said sheave, aweight aflixed to said rope.

3. In a cot for invalids substantially in two sections, each sectionbeing composed of a plurality of sub-sections, means for adjusting saidsections whereby the cot may be expanded or contracted, arms in twosections pivotally connecting the first named sections together, meansto make said arms rigid, and a brace to make said arms rigid with thelower section, arms having cogs thereon pivotally connected to the anarbor journaled transversely in the upper section, spur-wheels mountedupon said arbor to engage the cogs on the aforesaid arms, and means forrotating said spur wheels to position the free end of the upper sectionin anydesired position and. means to hold the cogs on the said arm incontact with the spur-wheels, a sheave affixed to the free end of theupper section and a rope to play over said sheave, a weight aflix'ed tosaid rope,a reticulated fabric stretched over the top section, and meansfor adjustably it to said section, and means for preventing said sectionfrom contracting when weigl'it is applied to the fabric.
